Chrysanthemum plant named ‘Yoerin’

ABSTRACT

A new and distinct cultivar of  Chrysanthemum  plant named ‘Yoerin’, characterized by its upright, outwardly spreading and rounded plant habit; freely branching habit; dense and full appearance; uniform and freely flowering habit; small daisy-type inflorescences with elongated oblong-shaped ray florets; light purple-colored ray florets and bright yellow-colored disc florets; natural season flowering in mid-October in the Northern Hemisphere; and good garden performance.

Botanical classification/cultivar designation: Chrysanthemum×morifolium cultivar Yoerin.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Chrysanthemum plant, botanically known as Chrysanthemum×morifolium, commercially known as a garden-type Chrysanthemum and hereinafter referred to by the name ‘Yoerin’.

The new cultivar is a product of a planned breeding program conducted by the Inventor in Salinas, Calif. and Alva, Fla. The objective of the breeding program is to create new garden-type Chrysanthemum cultivars having inflorescences with desirable inflorescence forms, attractive floret coloration and good garden performance.

The new Chrysanthemum originated from a cross-pollination made in October, 1999 in Salinas, Calif., of the Chrysanthemum×morifolium cultivar Alcala, disclosed in U.S. Plant Pat. No. 10,211, as the female, or seed, parent with the Chrysanthemum×morifolium cultivar Grace, disclosed in U.S. Plant Pat. No. 7,642, as the male, or pollen, parent. The new Chrysanthemum was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination grown in a controlled environment in Alva, Fla. in November, 2000. The selection of this plant was based on its desirable inflorescence form, attractive floret coloration and good garden performance.

Asexual reproduction of the new cultivar by terminal vegetative cuttings in a controlled environment in Alva, Fla. since January, 2001, has shown that the unique features of this new Chrysanthemum are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar Yoerin has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Yoerin’. These characteristics in combination distinguish ‘Yoerin’ as a new and distinct cultivar of Chrysanthemum:

-   -   1. Upright, outwardly spreading and rounded plant habit.     -   2. Freely branching habit; dense and full plants.     -   3. Uniform and freely flowering habit.     -   4. Small daisy-type inflorescences with elongated oblong-shaped         ray florets.     -   5. Light purple-colored ray florets and bright yellow-colored         disc florets.     -   6. Natural season flowering in mid-October in the Northern         Hemisphere.     -   7. Good garden performance.

In side-by-side comparisons conducted in Alva, Fla. under natural season conditions, plants of the new Chrysanthemum differed from plants of the female parent, the cultivar Alcala, in the following characteristics:

-   -   1. Plants of the new Chrysanthemum flowered about five days         earlier than plants of the cultivar Alcala.     -   2. Plants of the new Chrysanthemum and the cultivar Alcala         differed in ray floret coloration as plants of the cultivar         Alcala had darker-colored ray florets.

In side-by-side comparisons conducted in Alva, Fla. under natural season conditions, plants of the new Chrysanthemum differed from plants of the male parent, the cultivar Grace, in the following characteristics:

-   -   1. Plants of the new Chrysanthemum were slightly larger and more         rounded than plants of the cultivar Grace.     -   2. Plants of the new Chrysanthemum had smaller inflorescences         than plants of the cultivar Grace.     -   3. Plants of the new Chrysanthemum flowered more uniformly and         about three weeks later than plants of the cultivar Grace.     -   4. Plants of the new Chrysanthemum and the cultivar Grace         differed in ray floret coloration as plants of the cultivar         Grace had orange-colored ray florets.

Plants of the new Chrysanthemum can be compared to plants of the Chrysanthemum cultivar Kimberly, disclosed in U.S. Plant Pat. No 9,026. In side-by-side comparisons conducted in Alva, Fla. under natural season conditions, plants of the new Chrysanthemum differed from plants of the cultivar Kimberly in the following characteristics:

-   -   1. Plants of the new Chrysanthemum were more compact and more         rounded than plants of the cultivar Kimberly.     -   2. Inflorescences of plants of the new Chrysanthemum had smaller         discs than inflorescences of plants of the cultivar Kimberly.     -   3. Plants of the new Chrysanthemum flowered about five days         later than plants of the cultivar Kimberly.

Plants of the new Chrysanthemum can also be compared to plants of the Chrysanthemum cultivar Dinka, disclosed in U.S. Plant Pat. No. 12,915. In side-by-side comparisons conducted in Alva, Fla. under natural season conditions, plants of the new Chrysanthemum differed from plants of the cultivar Dinka in the following characteristics:

-   -   1. Plants of the new Chrysanthemum were more compact than plants         of the cultivar Dinka.     -   2. Plants of the new Chrysanthemum had larger inflorescences         than plants of the cultivar Dinka.     -   3. Ray florets of plants of the new Chrysanthemum were lighter         in color than ray florets of plants of the cultivar Dinka.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used. The following observations and measurements describe plants grown in Leamington, Ontario, Canada during the late summer and fall in an outdoor nursery and under conditions and practices which approximate those generally used in commercial garden-type Chrysanthemum production. One cutting was planted in a 15.25-cm container in mid-July. During the production of the plants, plants were exposed to natural season photoperiodic conditions with day temperatures averaging 26° C. and night averaging 18° C. Measurements and numerical values represent averages for typical flowering plants.
